shorting,

j is the object of my invention to provide a d vice ofsimplc COTlSiTI'HCtlOfi which may be easily set-in place and fixed in the body of concrete in desiredposition, and which will be secured with suilicient rigidity to, sustain'the Weight which such a device is igned'to carry.

is also an object oi my invention to provide a device for the purpose described which may be easily in jilace and fixed-inthe body 0% concrete in desired. position, and

which wili be secured with suilicient rigidity to sue i'ain the weight which such a device isdesig'ned to carry.

" it is also an object of my invention to provide a device for the purpose described which may be used with-reinforced concrete constructions, 1 in which t 1e reinforcing members are metal bars extending parallel with one another. The device is one which is adapted to embrace or. fit about the reinforcing bar, so that it inay be applied withoutrlifiicuity where the reinforcing bars'aire closetogether; it is also adapted for use with reinforcing bars of various cross sectionsuch as are now commonly used.

In the drawings: Figure 1 is a front elemomma .part in section, of a hangersoclzet embodying my invention and showing the manner in' which the same is our bedded in av concrete ceiling-g Fig. 2 is a front devation of the hanger-socket embedded in the concrete and showing the same used with a reinforcing bar of irregular section; Fig.

3 isa perspective view of the bangereocket shown in Figs. 1 and 2: Fig". 4 is a side eleva- .tion of another "town of hanger-socket also embodying the invention: Fig. 5 is a transverse vertical section of the same on the line A A of Fig. 4; and Fig. 6 is an inverted plan view of the same.

a is a tubiilar or hollow body which forms the socket proper. This is closed at the top and provided with oppositely directed lat eralarms 7), i), having at their ends upright bedded in the body of concrete.

I extensions 0, 0. The top of the body a has a recess (Z extending transversely to the lateral arms b, 6, open at its ends and preferably curved or trough-shaped.- ln settino;

the hanger-socket it. is placed withthe open end of the body a resting on the centering 0, and the concrete f is poured in above the centering, which, after the concrete is set, is

removed leaving the hanger-socket 61'1'1- For the purpose of holding the hanger-socket in place against. longitudinal displacement while the concrete is being applied,- a dowelpin 9 may be inserted through the centering into the socket. This may be either a metal 11in screwed into thc'socket or a wooden pin driven in. \Vhen the centering; is taken down the dowel-pin. is removed, leaving the socket open through the lower face oi the.

" concrete to receive the hanger or part which is to be suspended from it.

In applying the hanger-socket toreinforced concrete ceilings in which reinforcing metal bars extend parallel to one another through the concrete, the socket pieces may be arranged to embrace the reinforcing bars, as shown in the drawings. Nith round or twisted bars, the; bar inayfit in and extend through the recess d as is indicated in dotted lines in Fig. 1, and when the bar is of irregular shape having lateral arms or flanges k, the arms orflanges may extend over the lateral arms b, 7), with the central portion of the bar extending through the socket b, as is shown in Fig. The hanger-socket is thus adapted to be fitted about reinforcing bars of different crossisections such asare .now in common use. The upright portions these edgesaids in fixing the hanger-socket securely inthe concrete. The arms 7), 72, extending laterally from the top of the body of the socket into the concrete are however the principal means, in the, construction shown, of fixing the device securely in place.

"When the concrete is set the socket-is so rigidly fixed in place that it is capable of sustaining any reasonable Weight.

lOf

In the construction shown in Figs. 4,

such as is shown in Figs; 1, 2 and 3, Temploy an elongated box-like body at having a key-slot a to receive the hanger, the head of which may be inserted through the large portion a of the slot and then move longitudinally into the smaller part. For the purpose of strengthening the structure the lateral arms Z; and theouter wall of therecess (Z may be connected with the top of the socket body by webs z.

The manner of embedding the hanger-- socket of the form shown in Figs. 4, 5 and6, is the same as that employed with the hanger-socket shown in Figs. 1, 2 and 3, except that instead of a dowel-pin to hold the device against displacement it may be sc cured to the centering by tacks in the notches j in the sides of the bottom.

It will now be apparent that I have devised a novel and useful construction of a hanger socket which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

What I claim is as follows:

1. As an improved article of manufacture, a hanger socket for embedment in concrete ceilings and the like, comprising a body portion having a hollow member depending therefrom, the top surface of said body portion having a trough-shaped recess therein and the walls of said recess being extended laterally on opposite sides therefrom to form lateral supporting arms and upright exten- .sions projecting from said arms, the edges of said upright extensions having notches therein whereby upper anchoring terminals are formed, the notches in said upright extensions being adapted for the reception of concrete, whereby the device after,- ,being placed in position and surrounded with concrete is locked against vertical and lateral displacement.

2. The combination of a hanger socket for embedment in concrete ceilings and the like,

comprising a body portion having: a .liollow f member depending therefrom, the top surface of said body portion having a troughshaped recess therein and the Walls offlsaid recess being extended laterally on gopposite' sides therefrom to formv lateral supporting arms, said arms having upr ght extensions thereon, the opposite edges of said upright upper anchoring terminals are: formed, the

notches in said upright extensions being adapted for thereception of concrete, whereby the device after being placed in position and surrounded with concrete is, locked against vertical and lateral displacement,

lateral supporting arms, Sald. a,Im S,1h&.V iI1g upright extensions, the opposite edges of extensions having notches therein whereby said extensions having notches, therein,

whereby upper anchoring terminalsare formed, said notches being adapted for thereception of concrete whereby the device after being placed in position and surround ed with cement islockedagainst vertical and lateral displacement, andia has supported in said trough-shaped recess and extending transversely thereto, said bar havin laterally extending flanges adapted to e supported upon the laterally.ex flllilngsocket arms. j

In testimony of which invention, I here unto set my hand. r I
